For 1 credit I would suggest SAI in Epcot. I loved the atmosphere, thought that the food was excellent, and foud the service to be excellent.
Sanaa is a lovely option as well. I would use the time to explore the AKL resorts. I have not been to Kidani Village, but AKL is stunning, with plenty of animals to gaze upon and artwork throughout the building.
If you want the Boardwalk area think about Captains Grill in the YC, or Tratorria AL Forno on the Boardwalk. My DD dined at the latter and said it was hands down the best meal outside of Narcoossees on their July trip. After dinner you could enjoy strolling the Boardwalk,and stop for a cocktail or two.
